WARNING
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT USE THIS FAN WITH ANY SOLID-STATE CONTROL DEVICE.
WARNING
TO REDUCE THE RISK OF FIRE ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
a. Use this unit only in the manner intended by the manufacturer, if you have questions, contact the manufacturer.
b. Before servicing or cleaning unit, switch power off at service panel and lock panel to prevent power from being switched on accidentally.
When the service disconnecting means cannot be locked, securely fasten a prominent warning device, such as a tag, to the service
panel.
CAUTION
For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors. Take care when using cleaning
agents or detergents. Suitable for use in household cooking area.
WARNING
TO REDUCE THE RISK OF RANGE TOP GREASE FIRE:
a. Never leave surface units unattended at high settings. Boilovers cause smoking and greasy spillovers that may ignite. Heat oils slowly
on low or medium settings.
b. Always turn hood ON when cooking at high heat or when flaming food
c. Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan or filter.
d. Use proper pan size. Always use cookware appropriate for the size of the surface element.
e. Keep fan, filters and grease laden surfaces clean.
f. Use high setting on hood only when necessary.
g. Don’t leave hood unattended when cooking.
h. Always use cookware and utensils appropriate for the type of and amount of food being prepared.
WARNING
TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A RANGE TOP FIRE, OBSERVE THE FOLLOWING:
a. SMOTHER FLAMES with a close-fitting lid, cookie sheet, or metal tray, then turn off the burner. BE CAREFUL TO PREVENT BURNS.
If the flames do not go out immediately, EVACUATE AND CALL THE FIRE DEPARTMENT.
b. NEVER PICK UP A FLAMING PAN – You may be burned.
c. DO NOT USE WATER, including wet dishcloths or towels – a violent steam explosion will result.
d. Use an extinguisher ONLY if:
1. You know you have a Class ABC extinguisher, and you already know how to operate it.
2. The fire is small and contained in the area where it started.
3. The fire department is being called.
4. You can fight the fire with your back to an exit
WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
a. Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable codes and standards.
Including fire-rated construction.
b. Sufficient air is needed for power combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent
back-drafting. Follow the heating equipment manufacturer’s guideline and safety standards such as those published by the National
Fire Protection Association (NFPA) and the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) and
the local code authorities.
c. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
d. Ducted fans must always vent to the outdoors.
e. NEVER place a switch where it can be reached from a tub or shower.
f. Make sure the power is off before installing, wiring or maintenancing.

DUCTING
A minimum of 6” round or 3-1/4” x 10” rectangular
duct must be used to maintain maximum air flow
efficiency for single internal blower and 10” round
duct for dual internal and remote blower.
Always use rigid type metal ducts only. Flexible
ducts could restrict air flow by up to 50%.
Also use calculation (on page 5) to compute total
available duct run when using elbows, transitions
and caps.
ALWAYS, when possible, reduce the number or
transitions and turns. If long duct run is required,
increase duct size.
If turns or transitions are required; install as far
away from hood duct output and as far apart,
between the two as possible.
Minimum mount height between range top to hood
bottom should be no less than 26”.
Maximum mount height should be no higher than
36”.
It is important to install the hood at the proper
mounting height. Hoods mounted too low could
result in heat damage and fire hazard; while hoods
mounted too high will be hard to reach and will
lose its performance and efficiency.
If available, also refer range manufacturer’s height
clearance requirements and recommended hood
mounting height above range.
Vertical Ducting:
6” round minimum (CBI-xxxB blower)
10” round minimum (PBI-1100A and remote
blowers)
Horizontal Ducting:
3-1/4”x10” minimum (CBI-xxxB blower)
No horizontal option available for PBI-1100A or
remote blower
DAMAGE-SHIPMENT / INSTALLATION:
• Please fully inspect unit for damage before
installation.
• If the unit is damaged in shipment, return the
unit to the store in which it was bought for
repair or replacement.
• If the unit is damaged by the customer, repair
or replacement is the responsibility of the
customer.
• If the unit is damaged by the installer (if other
than the customer), repair of replacement must
be made by arrangement between customer
and installer.

WARNING FIRE HAZARD
NEVER exhaust air or terminate duct work into spaces between walls, crawl spaces, ceiling, attics or garages.
All exhaust must be ducted to the outside.
Use metal ductwork only.
Fasten all connections with sheet metal screws and tape all joints with certified Silver Tape or Duct Tape.

REPLACING LIGHT BULBS
CAUTION: Light bulb becomes extremely hot when turned on.
DO NOT touch bulb until switched off and cooled. Touching hot bulbs could cause serious burns.
Make sure all power is turned off and bulbs are not hot.
Remove by turning bulb counter clockwise. Note: Bulb does not unscrew; it turns 60 degrees, stops and
falls out.
If bulbs are difficult to turn due to prolonged use, firmly attach a glass suction cup approximately the
diameter of the bulb or use a rubber/latex glove and turn counter clockwise.
Replacement bulbs are available at specialty lighting stores. Purchase type MR16 (GU-10) 35W halogen.
For Zephyr part numbers please turn to page 20 of the manual.
